Teotihuacan

Teotihuacan was one of the largest cities on earth in the sixth century, a planned metropolis of apartment compounds, murals, and pyramids whose people left no readable script and no name for themselves. The name is later: the Aztecs found the ruins a thousand years after the city's fall and called it Teotihuacan, the place where the gods were created, building their own capital's cosmology on top of what they found. The Avenue of the Dead runs north past the Temple of the Feathered Serpent to the Pyramid of the Moon, with the Pyramid of the Sun, one of the largest pyramids in the Americas, west of the avenue.

It is managed as a ticketed zone open daily, and the climbing rules have been moving: the Pyramid of the Moon reopened to its first platform in May 2025 after conservation work, while the Pyramid of the Sun stays closed to climbing. At the spring equinox the zone runs a special security operation for the crowds that fill the avenue, many of them weekenders in white, and Nahua ceremonial groups remain part of the site's life, especially around the equinoxes; the respectful posture for visitors is to watch what they are doing before treating the pyramids as a photo backdrop.

Visiting

The National Institute of Anthropology and History's zone page carries hours, fees, and current climbing rules; open daily with last access late afternoon.
